I think they were referring to having to search your address here: http://bitcoincharts.com/bitcoin/, to check if there was a transaction. If it's there, it's pending the next blocks before it can be confirmed, that's what I understand. I always look there whenever my payments took like 6 hours before being confirmed. Sometimes I even see 0/offline? in the client but eventually it goes through. Depends on network speed. I hope I'm right.

Except that I know what you're talking about, and it *always* shows up on Deepbit, even before the transaction makes it into a Block.

Right now, you click the "Instant Payout" button, and nothing happens! Your account still shows the full amount of BTC, and it doesn't give you any feedback that a payment is on the way -- because a payment ISN'T on the way. The button is somehow broken.
